United States Patent 3,211,196 NOZZLES FOR DISPENSING GASOLINE INTO TANKS OF MOTOR VEHICLES George Rozinak, West View, Pa. (156 Carnation Ave., Pittsburgh 29, Pa.) Filed June 17, 1963, Ser. No. 288,284 1 Claim. (Cl. 141--392) The invention relates to gasoline dispensing valves of the type commonly employed at filling stations for supplying gasoline and the like to gasoline tanks of motor vehicles and it has particular relation to the outlet nozzle in dispensing the fuel.

The dispensing valves now employed are provided with a metal outlet nozzle and this type of nozzle has had a lot of criticism from the motorist, directed to the gasoline filling station trade because the finish of the motorists vehicles are scratched or marred by the metal end of the nozzles when the nozzle accidentally strikes the finish of the vehicle.

An object of the invention is to provide a nozzle for dispensing gasoline or the like into automobile gasoline tanks in which the metal nozzle is formed with a plastic protective member or tip adjacent the end of the outlet nozzle.

Another object of the invention is to provide a nozzle for dispensing gasoline into motor vehicle tanks, in which a protective member is provided that is easily and economically formed and applied to the nozzle adjacent the outlet end of the nozzle.

A further object of the invention is to provide a nozzle for dispensing gasoline or the like, which has a non-conductive end member to be inserted into the opening of the gasoline tank of the motor vehicle. These and other objects of the invention will be apparent from the description and drawings.

For a better understanding of the invention reference may now be had to the accompanying drawing forming a part of this specification, in which:

FIG. 1 is an elevational view of the invention, showing a dispensing valve having an outlet nozzle thereon formed in accordance with the invention.

FIG. 2 is a fragmentary longitudinal sectional view of an outlet nozzle formed in accordance with the invention, and

FIG. 3 is an enlarged fragmentary sectional view of the end of a protective member, formed in accordance with the invention.

The present invention provides a gasoline dispensing valve having an outlet nozzle secured thereon. The outlet nozzle being formed of metal or steel tubing is provided with a protective member or tip, formed of plastic, such as vinyl or polyethylene or the like. The protective member extends along the metal body of the nozzle toward the valve, covering the metal end of the nozzle, thus forming a structure that eliminates accidental marring or scratching of the vehicle body, when dispensing gasoline. It also provides a structure that substantially reduces the generation of the static electricity caused by the flow of gasoline.

In practicing the invention and referring to the drawing in detail, the invention provides a gasoline dispensing valve 10, having a body portion 11 including a control lever and an inlet 12 together with an outlet portion as indicated at 13. The inlet 12 is adapted to receive a hose connection 14 and the outlet 13 is threaded to receive an outlet nozzle 16, threaded as shown at 17. The nozzle 16 being preferably formed of metal tubing 18, cylindrical in cross section, which may be bent or shaped to impart a bend to the outer or discharge end of the nozzle is also provided with a protective member or tip 20 securely mounted about the outer periphery of the metal member 18. As mentioned above, the member 20 is formed of a plastic material, such as vinyl, polyethylene or the like and is of a molded construction, with the inside diameter 22 provided to form a hand press fit onto the metal portion 18. The inside diameter of the member 20 terminates in an inwardly extending flange member 24 of a length equal to the wall thickness of the metal portion of the nozzle. Extending outwardly from the metal portion of the nozzle, the member 20 is formed with a curved surface 25, circular in contour, forming a buffer area, which terminates at its outer periphery into a tapered surface 27, sloping from the outlet end toward the body portion of the valve, thus forming a protective member or tip which will prevent any marring or scratching of the finish of the automobile. It: is to be noted, that the length of the tip on the metal member of the nozzle is usually of a length that is substantially twice the diameter of the tubing. In the construction of the nozzle, the member 20 is pressed onto the outlet end of the metal member 18, with the heavy or thick end of the member 20 positioned at the outlet end of the nozzle. This is a press fit with the member forced along the metal portion of the nozzle until the flange 24 engages the metal end of the member 18, thus completely covering the metal end of the tubing. An opening 29 is provided for the escape of gasoline vapors when the nozzle is in operation.

It will thus be seen that I have provided a gasoline filling nozzle, which will not mar highly finished automobile surfaces, even with the nozzle being handled in a relatively careless manner. It will also be seen that I have provided a nozzle that will withstand relatively rough usage without any damage to the nozzle. Moreover, I have provided a nozzle that materially reduces static electricity caused by the flow of gasoline through the nozzle.

It is to be understood that the particular form of the apparatus shown and described and in particular the procedure set forth are presented for the purposes of explanation and illustration and that various modifications of the invention may be made without departing from the invention or the appended claim.

What I claim:

In combination with a conventional gasoline dispensing valve having a metal tubular nozzle mounted thereon comprising a plastic non-conductive protective member having an inner diameter formed for a hand press fit on the nozzle and an outside diameter greater at its outer end than at its inner end, an inwardly extending flange projecting from the outer end of the inside diameter of the plastic member, a buffer portion, rounded in contour extending outwardly from the flange to the outside diameter of the device, said portion cooperating with the flange to protect the finish of the vehicle when in use and an opening in the wall of the device, said opening extending through the nozzle to permit the escape of gasoline vapors when the nozzle is in use.
